The clipboard
 
You can use the clipboard to collect and paste multiple items.
The clipboard works with the standard Copy and Paste commands.

 
The item you cut or copied most recently will be pasted.
The office clipboard automatically copies multiple items when you do any of the following:
§ Copy or cut two different items consecutively in the same program.
§ Copy an item, paste the item, and then copy another item in the same program.
The collected items stay on the office clipboard until you exit all office programs or you delete the items from the clipboard task pane.
To open the clipboard, click on the launcher in the Clipboard group on the ribbon.
This will open a task pane on the side of the document.
